<p>最好使用pandas从您提到的URL读取JSON并将其保存到excel文件中。下面是它的代码:</p>
<pre><code>import pandas as pd
# Loading the JSON from the URL to a pandas dataframe
df = pd.read_json('https://restcountries.eu/rest/v2/all')
# Selecting the columns for the country name, capital, and the country code (as mentioned in the question)
df = df[["name", "capital", "alpha2Code"]]
# Saving the data frame into an excel file named 'restcountries.xlsx', but feel free to change the name
df.to_excel('restcountries.xlsx')
</code></pre>
<p>但是,在读取嵌套字段时会出现问题(如果您希望将来读取它们)。例如,数据集中名为<code>borders</code>和<code>currencies</code>的字段是列表。因此,加载后可能需要一些后处理</p>
